With the latest and greatest rifle cartridges out there jockeying for the top position on ammo mountain, more and more wonder rounds of years past are being relegated to obsolescence—or at least the manufacturers would like you to think so. Here are five calibers that are often overlooked but are just as capable as any new or veteran cartridge out there to do the job they were intended to do:
.300 Savage

Savage introduced the .300 Savage in 1920 as a replacement for their .303 Savage round chambered in their
Model 99 lever action rifle and why it has been lost in the shuffle is beyond me: it demonstrated better ballistic performance than a .30-30 Winchester with a 180 grain bullet traveling at 2,500 fps.

For decades the .300 Savage proved itself proficient on deer and even larger game, but when the .308 Winchester arrived (the design of which is actually based on the .300 Savage case) the new round, destined to become one of if not the most popular hunting round in North America, pushed its parent cartridge out of the limelight. Still there are lots old Model 99’s out there and some bolt actions chambered in the .300 Savage. Ammunition is still available and it can be readily handloaded.
.250 Savage

Before the .300 Savage came .250 Savage, designed by lawyer turned shooter, Charles Newton, though you may recognize this punchy cartridge by another name, the .250-3000. The round was called this because it could send with an 87-grain bullet downrange with a muzzle velocity of 3,000 fps—pretty impressive in 1915. Model 99 Savage rifles were also chambered in .250 Savage and, using a larger 117-grain bullet, this combo was capable of taking whitetail deer.
The .250 Savage was a very popular cartridge but lost a lot of ground when the .25-06 and .257 Roberts were introduced. Today you can still find them but it is getting a bit harder to find factory ammo, a good enough excuse to take up handloading.
.222 Remington

Ask ten hunters what their favorite varmint cartridge is and nine will probably tell you the .223 Remington, but there are a few dedicated hunters who still use a round they call the Triple Deuce, otherwise known as the .222 Remington.
The .222 Remington made its debut in the Remington Model 722 bolt-action rifle. With a 40 grain bullet capable of 3,500 fps it was a natural when it came to taking varmints from woodchucks right up to coyotes and it proved a very popular caliber in the 1950s and ‘60s as it wore out a barrel less than the competing .22-250 (also a Remington cartridge). None of this mattered though when, in 1964, the .223 showed up on the scene. Ballistically in-between a .222 Remington and a .222 Magnum, the .223 filled a niche for shooters and many couldn’t see past this. Today, rifles chambered in the Triple Deuce are getting harder to find although they are still out there if you’re up for a hunt and ammunition is actually very plentiful—to this day the .222 is still very popular in Europe.
.300 H&H Magnum

The .300 H&H Magnum has been declared dead more times than Detroit and just like the Motor City this round's performance and history is tenacity defined. Introduced in 1925, the .300 H&H won the 1000-yard Wimbledon Cup in 1935 and subsequently became a wildly popular big game caliber, boasting more power than the .30-06. Chambered in the
Winchester Model 70 and other bolt action rifles it enjoyed almost a 30-year reign until the .300 Winchester Magnum arrived and stole its crown.

Yet, as is often the case with disposed rulers, there is still a portion of the population chanting, “Long live the King”. In some circles the .300 H&H Magnum remains a very popular ammunition though it can be hard to find and quite pricey when you do. For handloaders, the .300 H&H is perhaps the classic all around big game caliber, capable of taking any animal in North America.
.444 Marlin

In 1964, Marlin introduced a new big bore lever action round with little more reasoning than there few out there in those days and the ones did exist were not very popular. The .444 Marlin was little more than a .44 Magnum case stretched out by one full inch to give it similar power to that of the old .45-70. Handloaders immediately found they had trouble with the cartridge; the bullets Marlin used were not getting the accuracy handloaders had hoped for and these reloading wizards soon determined the .444 Marlin worked better with bullets with a .432 diameter and not the more common .429 and .430 of the .44 Magnum.
Still, minute-to-deer hunters liked the .444 Marlin for its power—that is until the .45-70 Government was reissued and successfully planted its hooks in the hunting and cowboy action markets, dominated by large caliber lever rifles. Today though it can still be had, ammunition has become incredibly rare though it is still loaded for still hunters who own rifles in this caliber (and know what the gun is capable of).
There are more cartridges out there that have been pushed to side either by time or by some Johnny Come Lately round promising to do everything, far to many to list here. Some of them fell to wayside rightfully because of their own shortcoming and some still get the job done, as long as someone gives them the chance.
Surely rounds that took deer in 1935 can take deer in 2012. What’s your favorite “obsolete” cartridge?
